tinysend — Claude Code MCP server: newsletters and subscribers
Wires your agent into tinysend: mailing lists, subscribers, contacts, sending email. OAuth sign-in, so no API key to manage.
claude mcp add --transport http tinysend https://mcp.tinysend.comWhat tinysend does
tinysend exposes an email platform to your agent. It can create lists, add subscribers, draft and send posts, search contacts, and read project stats. Webhooks fire on events such as a sent post or a new subscriber, and you can set the sender domain plus a separate domain for the archive site.
The server lives at https://mcp.tinysend.com and speaks HTTP. Sign-in is OAuth, so the agent registers itself with no human in the loop; people who prefer a token can make an sk_... one in their account settings.
This suits agents that run a newsletter end to end: build the list, ship an issue, confirm the sender domain. A domain that has not passed its DNS check will not send mail, so run the sender check first.
What it helps with
- create a mailing list and add subscribers to it
- draft and send a newsletter post from the agent
- look up a contact by name or email
- set the sender domain and re-check DNS
- register a webhook for sent posts or new subscribers
Example prompts for the agent
- Create a list called Weekly Update and add [email protected] to it
- Draft a post with the subject Hello World and send it to the list
- Set the sender domain for this list and re-check DNS
